title: Type IV collagen is a heteropolymer with the formula C2D.
abstract: Native type IV collagen was purified from bovine kidney cortex homogenate by a method involving pepsin-solubilization and heat gelation. The near homogenous protein has a molecular weight of approximately 380K and the chain composition C2D. The subunits are linked by disulfide bridges.
